I think that it looks like a Pinworm. I have seen this before on a couple of horses. By any chance, have the horses been rubbing there butts on fences, boards, etc.? This is a big sign of Pinworms. I am not up on all the various kinds, but the pinworm is a pretty easy one to spot out.

Nope. She doesnt do the butt rubbing. I thought it looked a bit like a pinworm in some ways but what they say about them just doesnt fit. The description of how the horse acts and things fits a roundworm better but the pics I have seen just doesnt fit. So maybe were both wrong and its something different. I just dont know. Someone also said maybe its a piece of a roundworm and not the whole thing which is why it doesnt fit the look of one.

The vets out here really suck. I have had the vet out for her and they were no help. Im having a vet thats a friend that does small animal now, but used to do large animal take a look at them and see what he thinks.

As far as the eggs we cant seem to find them even under a sample is checked out. So the eggs havent helped us indentify.

I had a feeling and you all called it. The vet said they are pinworms. We have wormed her with the pastes but it isnt doing the trick. Gonna try a daily wormer to see if that will help. I got to see the pictures of the eggs ... it was very interesting

Thanks everyone... you were right on!!!

Now lets hope I can get my horse rid of them. DoBeSassy - I agree. Im trying... my poor baby... I feel so bad for her and guilty...

We double dosed with Strongid T (Pyrantel Pamoateoral) and the worms started comming out that night. The other horse that was singled dosed had worms out the next day. Both horses released worms for a few days then we singled dosed 2 weeks later

Sadly for some reason I guess its my bad luck striking we have done what was supposed to be done with the paste wormers, even had the vet out on what he thought we should do. And it has not taken care of my horses worms Its been a big battle. It stresses me out so bad, and I feel so guilty.

The 1 we used was one the is added to grain (but not the daily wormer) and can be double dosed safely. Made by pfizer (sp?) Our vet said this was the best way to go that it will work better then the paste

Don't worry don't feel guilty, you'll get them gone

We normally worm every two months. But this filly has been wormed every month for the last few months switching off on different kinds every month. The first time we discovered the worms she was wormed two week later and well do the same thing this time. We thought we had the worms as she started to gain her weight back and look more healthy. But then here in the last month shes got her belly back again. Thats why Im thinking Ill try the daily wormer. Seemed when it comes close to time for her to be wormed again shes wormy all over again. This all started because my filly has an extra large belly and a thick winter coat much thicker then the others that she isnt losing very quickly. The vet has been out but he doesnt seem to think it any big deal. Maybe Im just a bit paranoid But this is one of my babies and I am fairly new to having horses as an adult. We boarded my arabian mare somewhere and it was full care. Weve had our own place and more then one horse for a little over a year. Its much different.
